degree darajé (#) Fr.: degré 1) Subdivision of an interval in a scale of measurement. From O.Fr. degré, from V.L. *degradus "a step," from L.L. degredare, from L. → de- "down" + gradus "step." Darajé, from Ar. darajat "step, ladder." |
degree of freedom daraje-ye âzâdi (#) Fr.: degré de liberté Of a → mechanical system, the number of → independent variables needed to describe its configuration. |
degree of ionization daraje-ye yoneš (#) Fr.: degré d'ionisation The number of electrons a neutral atom has lost in an ionizing physical process (radiation, shock, collision). In spectroscopy, the degree of ionization is indicated by a Roman numeral following the symbol for the element. A neutral atom is indicated by the Roman numeral I, a singly ionized atom, one which has lost one electron, is indicated by II, and so on. Thus O VI indicates an oxygen atom which has lost five electrons. → degree; → ionization. |
degree of polarization daraje-ye qotbeš Fr.: degré de polarisation The ratio of the intensity of polarized portion of light to the total intensity at a point in the beam. → degree; → polarization. |
degree of stability daraje-ye pâydâri Fr.: degré de stabilité Statics: The → energy that must be expended to permanently disturb a specific state of → equilibrium of a body. |
degree of vertex daraje-ye târak Fr.: degré de vertex |
first degree equation hamugeš-e daraje-ye yekom Fr.: équiation du premier degré A equation in which the highest → exponent of the → variable is 1. Same as → linear equation. |
polarization degree daraje-ye qotbeš (#) Fr.: degré de polarisation → polarization; → degree. |
square degree daraje-ye câruš Fr.: degré carré A solid angle whose cone is a tetrahedral pyramid with an angle between its edges equal to 1°. 1 square degree = 3.046 x 10^{-4} sr = 2.424 x 10^{-5} solid angle of a complete sphere. |
